well mongo 33's on the lwb would be doable but your gonna be on the end of a strap ALOT and really may not enjoy the trip fully i also highly recommend all trucks have proper armor for rockers and gas tank. What gets the 4dr's is that big <img src="/forums/images/graemlins/butwiggle.gif" alt="" /> it hangs on everything tucking that gas tank up into frame rails helps alot and so do 35's.
I hate scaring people off from these trips because they are a ton of fun and the views are amazing BUT i don't wanna lie and get you guys into something your not ready for these trails are very hard and if any truck isn't properly setup its gonna slow the whole group down. There have been some pretty nightmare mitsu trips in the sierra's in the past trust me on this. <img src="/forums/images/graemlins/evil.gif" alt="" />
